It's not the number of codes, but which ones in particular. Suggestion although it has it's own possible flaws. Have a place for users to post the codes they use and by their specialty. Obviously we all need certain basics like office visits, CPE, and other everyday codes that are fairly universal.

But anyway, at Nancy's IPA/PO we get fee schedules with certain codes on them, but they are taylored by basic specialties. Members are welcome to send in codes they are thinking about or find a need for and they are added to the next update. But this way the list is not out of control for anyone user, but we all have almost all the codes we need. So perhaps a Peds/Family Med one, a GYN, A GI, and so on and so forth, as needed. And maybe one that is a compilation of all the codes for those who might want access to more for some reason. And again the ability to suggest and add codes is the key. But this might end up being more work than other methods, but it's a suggestion.
